Hunters. As those entrusted with the vital role of standing against monsters, they all lead thorough and busy lives. Since they fight on the brink of life and death every day, leisure is hard to find.

Ah, except for one person.

Freelance Hunter, Jang Jiyu. An enigmatic figure who operates alone, belonging to neither the Association nor a guild. She usually spends her days in a relaxed manner, only to appear out of nowhere and clear a Gate whenever one opens nearby.
